justinfx / weakmethod_callbacks_qt.py

Last active December 20, 2015 19:29

Example of having thread-safe callbacks from threads back to the main event loop, in PySide/PyQt4. Also adds support for weak method references to the callback, so as not to call something when the original object might have been deleted. Merges forked examples from both: http://code.activestate.com/recipes/81253/#c5 and http://code.activestate.…

	"""
	ActiveState:
	http://code.activestate.com/recipes/578634-pyqt-pyside-thread-safe-callbacks-main-loop-integr/

	ref and proxy classes are based on:
	http://code.activestate.com/recipes/81253/#c5

	Modified proxy to support a quiet concept for callbacks that can
	simply pass if they were not valid, instead of raising an exception.
